For a soap created by the cold method what would you expect the pH of the soap to be like immediately after cooling acidic, basic, or neutral? Use evidence to explain why you believe your answer is accurate.
For the synthesis of soap by cold process, oil and sodium hydroxide lye are used. As sodium hydroxide is strong base, immidiately after the cooling, soap is expected to be basic and pHpH will be higher than 8.0.
If we use a red litmus paper on the soap, the litmus paper will immidiately turn blue which verifies that the soap is basic.

Date Soap Name Partner Answer the following questions. • From the pH test, what is one property of soap that you now know? Hint: phenolphthalein turning pink indicates 2. Assume you have washed all NaOH away. 2. The Ca"? and Mg2 tests should have given a solid material with "Your Soap Solution." These solids are insoluble soap salts commonly known as "Bath Tub Scum." • From your results, what can you conclude about the hardness of our tap water? Explain...
After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer. The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings? my topic from week 2: Is handwashing effective...
A.Determine whether Co(ClO4)2is acidic, basic, or pH neutral. Explain. B.Determine whether KF is acidic, basic, or pH neutral. Explain. C.Determine the pH of a 80.0 mL quantity of 1.75 M HNO3 solution. Draw a picture of what’s in solution if you add 4 molecules of HNO3 to water. D.What is the pH after 20.0 mL of 1.25 M Ba(OH)2 is added to the solution in question C? Does your answer make sense? Draw another picture of what’s in solution after...
What medium would you expect when balancing out the following equation? MnO4 (aq) + SO3(aq)2 → SO4(aq)2- + MnO2(s) Acidic Basic Solid Neutral

What is the pH of a solution with a H2O* concentration of 2.7 x 10 M? Is this solution acidic, basic, or neutral? Show the steps in your calculation. Answer 7. What is the pH of a solution with a OH concentration of 5.53 x 10-M? Is this solution...
What medium would you expect when balancing out the following equation? Cr2022-(ag) + Mn2+(aq) – Cr3+(aq) + MnO2(3) Acidic Cannot be determined Basic Neutral
After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer. The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings? Compare qualitative and quantitative research designs and outline...
1. Why is it important to monitor the pH of wine? 2. In examining the pH scale, determine which values are acidic, basic, and neutral. 3. Explain in detail and show your calculations as to how you will make 100.0 mL of 0.050 M NaOH from a 1.00 M stock solution. 4. What is the purpose of a “scout” titration?
please help! thank you!
O ACIDS AND BASES Making qualitative estimates of pH change Each row of the table below describes an aqueous solution at 25 °C. The second column of the table shows the initial components of the solution. • Use the checkboxes in the third column to explain the type of the initial solution. The fourth column describes a change in the solution. • Use the fifth column to predict how the change in the solution will change...
